LISTEN: This Is What Your Voice Should Not Sound Like In A Job Interview

When you go into a job interview, you’re being judged on so many different things - far more than your knowledge of the industry. Many employers asses how you dress, your body language, how enthusiastic you are. For some women a new Duke study shows that even your voice may play a factor.

The study, conducted at Duke University’s Fuqua School of Business, analyzed voices from males and females and discovered that a certain creaky and rumbling low-pitched tone, called "vocal fry" made the speaker seem “less competent” to listeners. Though "vocal fry" was perceived as a negative factor in both sexes, it was perceived as more negative in women than in men.

The study enlisted 800 online listeners. Half were assigned to listen to female voices and the other half listened to male voices. Each listener was then given seven random vocal clips and were instructed to rate the voices on competence, education, trustworthiness and attractiveness. Bill Mayew and Mohan Venkatachalam, the researchers behind the Duke study, found that listeners rated women who spoke with vocal fry lower in all of the categories.

“One possible reason for this is that a lowered register is seen as more atypical for women than men,” Mayew said. “What was even more interesting is that female listeners perceive vocal fry more negatively than male listeners.”

“In a standard interview setting, gut instinct plays a large role in whether a candidate is hired,” Venkatachalam said. “Vocal fry could sway that judgment against a candidate.”

So take out your smart phone -- record a short bit of your voice and listen back. Does your voice fry? Perhaps just a little change in your voice may be what it takes to get that job or raise that you deserve.
